Credit it to the new found 'friendship' between Deepika and Ranbir but if insiders are to believed, the 'chemistry' between the duo can't be ignored, especially on the sets where they are shooting for 'Yeh Jawaani Hai Deewani'.

"When they did 'Bachna Ae Haseeno' together, she was just starting off her film career. However post 'Cocktail' there is a renewed confidence that Deepika is carrying. Ranbir has noticed that as well. Deepika knows that it is time to up the ante now and her Western characterisation is further helping the cause. Not just has she gone ultra glam for the film, she has even turned far more intuitive in front of the camera. That's helping her get the romantic scenes perfectly right in the film which is only adding on to her chemistry with Ranbir", informs a source attached to the film.

What is further adding on to this is the fact that director Ayan Mukherjee too has moved on from a plain and simple setting of 'Wake Up Sid' to make something ultra stylish and hip in the form of 'Yeh Jawaani Hai Deewani'. With Ranbir too looking at a far more contemporary setting after a rather sombre 'Barfii!' and Deepika allowing her ultra glam personality to do the talking, this Karan Johar production could well turn out to be one of the most good looking affairs in the offering.
